The means employed to this end preferably consists of two pairs of longitudinal ribs of gradually increasing' or taper ing cross-section, provided on the two opposite side walls of the top end of the magazine tube, the upper ends of the ribs being wider and projecting farther into theroom of the magazine tube than the lower ends thereof due to the tapering shape of the ribs. Further the front ribs of the .two pairs, that is to say, the two opposite ribs nearest the barrel end of the firearm, are shaped to project to a farther extent into the room of the magazine tube, in accordance with 'a pre-` determined ratio, than the rear ribs of the two pairs.

A still further object of the present invent-ion resides in an improved construction of the follower employed in connection with the improved magazine. In the rearms as hitherto constructed orV designed a particu lar element or member is employed for stopping the follower or limiting the number of cartridges to be insert-ed into the magazine. According Vto the present invention the follower is provided with downwards Vextending shanks adapted to guide both itself and the controlling spring and to act at the same time as a stoppin@ means for automatically limiting the numtber of cartridges to be inserted into the magazine, or in other words, to just strike on the fixed bottom of the magazine tube when in the loading operation the predetermined number of cartridges has been inserted into the magazine. In this way I K combine and realize in a very simple, efficient and inexpensive manner the two advantages of automatically limiting the predetermined load and reliably guiding both the follower and the controlling spring during the up and down movement thereof incident to the loading and discharging proceedings. Y

Y To the accomplishment of the foregoing and related ends, the invention then consists of the means hereinafter fully described and particularly pointed out in the claims. The annexed drawing and the following desci'iptionset forth in detail certain mechanism embodying the invention, suchy disclosed means constituting, however, but one of various mechanical f orins in which the principles of the invention may be used.

In said annexed drawings: Figure 1 shows the magazine in side view with the Vlower end broken away and with the magazine holder indicated by broken or dot-aiid-dash lines; Figure 2 is a view iii vertical Asection on the lineV II-II of Figure 1; Figure 3 is a fragmentary side view of a modified forni of the magazine with the holder engaging the rear side of the magazine; Figure Vt is a view in horizontal section taken on the line IV--IV of Figure 3; Figure 5 is a fragmentary view of a further modification of the magazine with the reinforcing inember firmly attached thereto to form the rear wall thereof; Figure 6 is a sectional view of the upper part of the modification shown in Fig. 5; Figure 7 is a similar section of the lower part thereof, while Figure 8 is a like section of a modified construction of the reinforcing member interconnected with the magazineg'Figure 9 is a view in vertical section of a further modification of the niagaziiie, partly broken off and with the holder or casing carrying the magazine, and the cartridges shown in broken and dot-anddash lines;'Figure 10 isv aV view in section Ytaken on the line X-X of Figure 9g`Figure ll is a ,view in longitudinal vertical section of the upper end of the magazine shown in Figure 9 with a few cartridges therein and -with'the follower removed; Figure 12 is a view in top plan of the parts illustrated in Figure 10; Figure 13 and Figure 14 are Afront and side elevations, respectively, of `the follower constructed according to the present invention; and Figures 15 and 16 are corresjionding sectional views of the follow- -ei inserted in the bottom end of the maga- :zine

Referringrto the embodiment of the invention shown in Figures liand 2 the U- shaped reinforcing member 2 is firmly united with the upper end of the magazine body l by soldering or in any other suitable way. ,The length of the member 2 corresponds to the length of the holding sleeve taken from the top forming the discharging orifice down to the projections or noses 3 formed in the members 2to act as an abutment oi' stop for the lower end of the holding sleeve so that the latter will rest thereon when the magazine is fully pushed home, as shown in F ig ure 1. One wing or shank of the U-sliaped Amember 2 is provided with a comparatively wide recess or aperture- 4 for the magazine .holder to engage therein while at the same vtime the two noses 3 act to limit the insertion of the magazine into the holder. In the modification shown in Figures 3 and 4 wherei'in the holder engages the rear hind edge of the magazine, the rear wall of the magazine `tube is shaped to form a longitudinal smooth V channclled rib or shoulder for the bottom ond of the cartridge shell to freely and smoothly Yslide thereon. Also in this modification the cartridges thus are prevented from coming in contact with the magazine holder when4 they are pushed upwards in the magazine by the spring controlled follower, although the holder engages into recesses provided in the oneY rear corner cf both the reinforcing member 2 and the magazine tube.

' It will be seen that in both embodiments shown in Figures 1 to 4 wide engaging surfaces may be offered to the magazine holder so that even in case of abnormally long and heavy magazines made of thin metallic sheets modification the overlapping 4magazine holder vto the full `length. of

such magazines are safely prevented from other lshocks a firearm is liable to It will further be seen-that the engages the i reinforcing member or covering and not the magazine body itself, so that all disturbing lateral cavities, recesses or grooves are entirely dispensed within the magazine body andthe latter constitudes a smooth faced channel throughout'fromfend to end wherein the be exposed.

cartridges can freely move towards the .dis-

charging'opening or lips without Vstriking on i any impediments or obstacles' during' the upward Vmovement,iwith the resultfthat jam-V ming and loading stoppage .will be entirely avoided thereby." l i ln the modifications illustrated in Figures 5 to 8 the' U-shaped reinforcing member or covering 5'likewise serves the purpose of bracing the lips of the magazine body' 1 vand is 'also-equipped with laterally project` ing noses or lugsv for the holder-,to abut'thereagainst. In these embodiments,however,the

' lU-shapedgmember orcoverin'g 5 is elongated the magazine body 1.

the covering 5 will form the rear end wall of the magazine.

The elongated orlower end of the lreinforcing covering possesses two lateral anges of less width than that of the flanges of the upper part of the covering provided with the projecting noses or lugs7 as will be clearly seen on inspection of Figures 6 and 7.

flanges of the covering 5 and the maga-zine body 1 are firmly united by soldering throughout the whole length thereof. In trated in Figure 8, the lower or elongated part of the reinforcing covering 5 are bent are bent twice outwardly so that, when the parts are assembled, the retroverted flanges thereof will engage in and be firmly connectbv the spring controlled follower 11, as usy ually, but the uppermost cartridges of the two rows are automatically and gradually displaced to occupy a, so to say, one row position with the topmost cartridge in charging orifice formed by the two rein- 'are sha-pedi magazine ,tube In this verably l make the of" she'etmetal spo-that the bridge andthe the modification illus-.v however, the flanges of" twice inwardly and the cooperating flanges of the magazine body its .movements in both the disy forced flips, whence the topmost cartridgeV will -be'discharged, upon firing of a shot, so as to 'occupy a-'position in alinement with the bore of the barrel prior to the advance of the'cartridge into the barrel. In the embodiment illustratedin Figures-9l to 12 the magazine tube 7 is providedwitlia pair of Ling form gradually decreasing, as regards width andheight,from the top towards'the bottom 'of the magazine, the two rear ribs S,see'--FigureV 10, being of somewhat less "height than the y "forithe, purpose of gradually displacing the uppermosty 'cartridges' two opposite front ribs 10,

automatically from a 'verticalv inclined position into `aliorizontal slantiiigposition, as'will be readily under'- st'ood upon comparative vinspection of Figures 10 and 11. The slanting'orcrossing position .of the three' or yfour uppermostcartr'idges forming wliat'may be said a single a verticali row only, prevents the marginal pushed out of the orifice of the magazine, noV

' obstruction can take place and, therefore, Ano 'loadingstoppage will occur.

j'As 'shown in Figures 13 to 16 the follower consists of Yafsubstantially U-shaped member 12 whereof the interconnecting median portion or bridge constitutes the follower prop- 'erly Aspeaking and the two shanks'l and 14 to conform to the shape of the i and tobe adapted to embrace and guide the spring of the follower. ,Preffollower of aV single piece Shanks thereof are integrally connected with each other and of required rigidity. .In order toi increase the rigidity and stability of the bridge portion the latter may be corrugated lengthwise', as shown in Figure 16.`

In the operation of loading the magazine by inserting cartridges therein, the shanks of the follower strike the bottom 17 of the magazine just when the last one of the predetermined number of cartridges has been inserted so that further cartridges cannot be iilled in. The follower thus determines and limits the load and the two Shanks 13 and 14 thereof act atthe same time to both the' controlling spring during expanproperly guide sion-or compression and the follower itself in directions.

I have herein described and shown several practical constructions of f my present improvements, but -it will be apparent that the "magazine and its constituent'parts are susceptible of embodiment in variousother;al-A ternativeforms, and I, therefore, reserve the CTI privilege of resorting to. all such legitimate for the purpose set forth.
